Abstract: A thioacylation of the proper amines to yield 20 substituted monothiourethanes,
16 of which were so far not reported, is described. Interpretation
of infrared spectra of compounds thus synthesized makes it possible to
ascribe in the case of aromatic monothiourethanes 3 characteristic absorption
bands at 1520, 1360 and 930 cm-1 to the - N H - C = S group.
Ultraviolet absorption spectra of monothiourethanes reveal in the
220 —360 nm region an intense absorption band that could be associated
with tho so called ,,N" conjugation of the chromophore system - N H - C = S .
The influence of the substituent on tho localization and character of tho
absorption bands is discussed.
